Definitions
- This invention relates to laminated product combined with processes for molding and, more particularly, to a method for applying facing to fiberglass.
- Fiberglass is a popular insulating material used in many industries. In particular, it is frequently used in molded form to serve as a sound deadening and heat insulating element surrounding engines or on the walls of engine compartments. Despite its valuable properties, uncoated and unfaced fiberglass can present problems of deterioration of product and irritation to the user. First, many workers are reluctant to use fiberglass, perceiving it to be uncomfortable and irritating to handle. The second problem is that fiberglass, by its nature, is easily abraded and torn. When cut, fiberglass may produce an irritating dust at the cut edge due to the friable nature of the material.
- the process of this invention which produces a molded, completely enveloped fiberglass product in which all surfaces and all internal and all external edges, fastening holes and cut-outs are covered by a laminated fabric facing to enhance appearance, reduce abrasion, improve comfort in handling, and provide improved durability.
- the molded fiberglass workpiece is placed in a second heated press mold with a sheet of facing fabric on its top and bottom.
- the facing fabric is preferably polyester which has been pretreated with a thermoset binder, preferably a vinyl chloride copolymer.
- One side of the fabric is also coated with an adhesive, preferably a water based, heat activated, acrylic adhesive.
- the second heated mold is very important it is of similar configuration as the molded fiberglass workpiece, but it contains, additionally, a circumferential area to compress the facing fabric to form a lip around the fiberglass.
- the enveloped fiberglass workpiece is trimmed, preferably by a die cut, so that the resultant product is a fiberglass molded piece with all surfaces including inner and outer edges enveloped in facing fabric which totally adheres to the workpiece and ends in a lip of fabric bound to fabric at all edges.
- the facing fabric encapsulates the fiberglass with no folds or bunching and with no fiberglass exposed at any edge.
- Another embodiment is particularly suitable for pieces with straight edges and little variation in topography.
- a blank fiberglass mat is placed between two sheets of the preferred facing fabric.
- the mat and the fabric are molded together in a single molding operation.
- This mold has areas of severe edge compression incorporated into its design. When trimmed, the resultant product is completely covered on its surfaces with the facing fabric and at its edges is extremely compressed so that only a minimal, ie. about 1.0 millimeter portion of fiberglass edge is exposed sandwiched between the facing fabric.
- FIG. 1 is a schematic illustration of the process steps used to produce the molded and completely enveloped fiberglass product of this invention.
- FIG. 2 is a cross section of the fiberglass end product taken on lines 2--2 of FIG. 1.
- FIG. 3 is an isometric view of a complex molded fiberglass product with an irregular topography and completely enveloped in facing.
- FIG. 4 is a cross section taken on lines 4--4 of FIG. 3.
- FIG. 5 is a cross section taken on lines 5--5 of FIG. 3.
- FIG. 6 is a schematic illustration of the process steps used to produce an alternative embodiment of a molded and double-faced fiberglass product in which edge compression is illustrated.
- FIG. 7, taken on lines 7--7 of FIG. 6, is a cross section of the product produced by the alternative embodiment of FIG. 6.
- Uncured fiberglass preferably supplied in roll 10
- Uncured fiberglass is trimmed by cutter 11 to yield an appropriately sized uncured fiberglass mat 12.
- Uncured fiberglass is the raw mat of which the thermosetting binder has not been cured by temperature. It is soft and has slightly tacky properties.
- Fiberglass 10 is rotary spun fiberglass which includes a 20% thermosetting binder which is sprayed on as the fibers are spun out to filaments, as is well known in the art.
- Mat 12 is fed into press 14 which has been fitted with heated mold 16.
- the process of this invention is especially preferred for enclosing or laminating molded workpieces of irregular topography for use as acoustical insulation pieces for automobiles, i.e. hood insulators, fender insulators, and other engine compartment insulators as well as interior components.
- Mold 16 is shown with an irregular contoured configuration schematically corresponding to a piece used as insulation in the fender of trucks and will be discussed in detail in subsequent Figures.
- Heated mold 16 operates at a preferred temperature of about 400° Farenheit to about 450° Farenheit.
- Press 14 operates at a preferred pressure of about 400 to about 1200 pounds per square foot (psf), depending upon the density of the required fiberglass finished product.
- Molded fiberglass mat 18 is removed from mold 16 and excess fiberglass 23 is cut from the edges of the mold. It is preferred that die cutting apparatus 20 with die 22 be used for trimming, but water jet or knife cut are acceptable trimming procedures and are well known in the art.
- the trimmed fiberglass workpiece 24, now in its semi-final form with top 25 and bottom 27, is then fed through two rolls 26 and 28 of facing fabric.
- the facing fabric be a non-woven polyester fiber blend impregnated with a thermoset binder, preferably vinyl chloride copolymer. Rayon and other durable and abrasion-resistant fabrics may be used and an acrylic binder is also possible, but for durability and wrinkle-free application, a polyester fabric with the specified binder has proven most satisfactory.
- One surface of the fabric is also preferably pre-coated with a water based, heat activated, preferably, acrylic adhesive 99.
- Second press 34 has heated mold 36 which is similar in configuration to mold 16 in heated press mold 14, but its entire outer circumference is enlarged to produce a compressed lip around every outer edge, as will be discussed in detail with reference to FIG. 2 and other Figures.
- the circumferences of any interior cutaways or apertures are smaller than those of mold 16 so that mold 36 produces a lip around all interior edges, such as fastening holes and cut-outs, as well as exterior edges.
- Molded workpiece 24 and fabric sheets 30 and 32 are then molded and sealed together by heated mold 36. It is preferrred that second heated mold 36 operate at a temperature of about 250° Farenheit to about 300° Farenheit and the second press 34 with a pressure of about 400 pounds per square foot. The pressure selected must be great enough to compress and adhere the fabric to the insulation. Temperatures must be adequate to activate the binder in the fabric and to fuse the adhesive.
- FIG. 2 a cross section of finished product 44 made in mold 36 of FIG. 1, and taken from lines 2--2 of FIG. 1, is illustrated.
- mat 12 is seen molded to have an uneven contour or topography on top surface 25 and a relatively flat bottom 27.
- Top surface 25 has been fused to facing fabric 30 and bottom 27 to facing fabric 32 to form finished product 44 with a rounded top and flat bottom.
- a lip 37 is seen.
- product 44 in this example a fender insulator
- product 44 is about 25.4 mm thick at its center, it is seen to be compressed at its edges until only two layers of facing fabric remain sealed together with no intermittent fiberglass to make lip 37 and completely envelop fiberglass workpiece 24 with a thickness of about 0.5 mm at lip 37.
- Product 70 is a hood insulator which is shaped to be placed inside the hood of an automobile.
- Product 70 is described in detail.
- Product 70 is approximately three feet wide and two feet high. It is approximately 45 mm thick in general area 94, except for areas molded to fit around protrusions on the vehicle's engine, and is about 6.0 mm thick at its edges. It also has many apertures and depressions to accommodate various protrusions on the vehicle hood.
- product 70 is only the thickness of two layers of fabric, about 0.5 mm., and has no fiberglass
- product 70 is compressed to a thickness of about 6.0 mm.
- aperture 71 is provided to receive a mounting fastener.
- Circumferential lip 80, immediately surrounding aperture 71 is a lip formed of only two layers of fabric and, again, is about 0.5 mm thick.
- Compressed area 77 immediately surrounding lip 80 is compressed fiberglass encapsulated by two layers of fabric and is approximately 6.0 mm thick. All areas 78, 82, 83 and 74, and cut-out area 96 are similarly molded.
- Edge areas 84, 85, and 86 are similar in that their edges 92 are only the thickness of two layers of fabric. Areas 83, 84, 85, and 86 include apertures 83a, 84a, 85a, 86a and 86b respectively, which are surrounded by lips as described in reference to area 78. Completely surrounding product 70 is a circumferential fabric lip 92 which is approximately 0.5 mm thick and about 3.0 mm wide. Areas 88 and 90 are compressed at their interior boundary 89 to fit around the indentations in the car hood and to provide clearance to the vehicle's engine. At boundary 89, the mold has compressed to a thickness of approximately 4.0 mm.
- each interior and exterior edge is completely enveloped with laminated fabric to form a fabric lip. No fiberglass is exposed and the facing fabric fits smoothly to all contours.
- the fabric-to-fabric lips are narrow and flexible, and thus do not interfere with the snug placement of the insulator in the hood of the vehicle.
- FIG. 4 a cross section taken on line 4--4 of FIG. 3 illustrates the multi-layers of the fiberglass product of this invention.
- General area 94 is aproximately one and one half inches thick, compressed areas 93, 95 and 74 are approximately 6.0 mm thick, and lips 92, 97, and 73 are approximately 0.5 mm thick. It can be seen that even at apertures 72 and 83a, no fiberglass is exposed because all surfaces are encapsulated with fabric to completely envelop the fiberglass.
- FIG. 5 a cross section taken on line 5--5 of FIG. 3 illustrates aperture area 78 as an example of all the apertures in product 70.
- Aperture 71 is surrounded by lip 80.
- Adjacent to lip 80 is compressed area 77 which spans the distance between lip 80 and rounded surface area 94, all as previously described in reference to FIGS. 3 and 4.
- FIG. 6 an alternative embodiment of the process of this invention is illustrated schematically.
- the process described in FIG. 6 is useful for straight edged solid workpieces in which the topography is not multilevel and in which there are few edges and no apertures.
- Fiberglass mat 50 is placed between two sheets 52 of facing fabric.
- facing fabric 52 is preferably on rolls and fiberglass mat 50 is placed on the sheets as they come off the rolls, adhesive sides 51 towards each other.
- pieces 58 and 64 are shown rotated 90° to better illustrate their shape.
- fiberglass mat 50 is spun fiberglass with at least 20% binder, although any fiberglass is suitable to the process.
- Facing fabric sheets 52 are preferably polyester with a vinyl chloride copolymer binder; and each sheet 52 is coated on side 51 with a water based, heat activated acrylic adhesive.
- Adhesive sides 51 of fabric sheets 52 are placed facing fiberglass mat 50. Sheets 52 surrounding mat 50 are placed in press 54 which contains heated mold 56. After applying heat of about 375°-400° Farenheit and pressure of about 600 pounds per square foot to the fiberglass and fabric, a molded, faced workpiece 58 is produced. Workpiece 58 is seen to have stepped down area 66, aperture 67, and edges 65. Trimmed piece 64 is compressed at its edges to produce stepped down area 66 and then pinched at its edges to form edge 65. The same stepping down and pinching occurs at aperture 67 which is surrounded by stepped down area 69 and pinched edge 68. More pressure is required in this embodiment in order to pinch the fabric and insulation enough that the wastage 63 will easily break off.
- Mold 56 is shaped so that all the outer edges of the finished product are first stepped down to area 66 and then pressed to a very fine edge 65 (approximately 0.5 mm), the edge being only a small fraction of the thickness of the center of the trimmed piece 64.
- the resultant product has extremely narrow edges composed of two layers of fabric 52 sandwiching an extremely compressed layer of fiberglass.
- Trimmed workpiece 64 is a product intended to be used in automotive components, such as a fire-wall insulator, is relatively flat on both surfaces and includes only one aperture 67.
- Mat 50 is compressed at its edges to a thickness of about 0.5 mm to form a lip edge 65.
- Fabric 52 is sealed to both top and bottom surfaces of product 64, so that the only exposed fiberglass is on the lip edges 65.
- Aperture 67 is likewise pinched to form a stepped down area 69 of about 6 mm and edges 68 of about 0.5 mm so that mat 50 and fabric 52 easily punch out of area 67 to form an aperture.
- Aperture 67 is likewise pinched to form a stepped down area 69 of about 6 mm and edges 68 of about 0.5 mm so that mat 50 and fabric 52 easily punch out of area 67 to form an aperture.
- a very fine edge of fiberglass may be exposed.
- the first process is applicable to molded fiberglass pieces having complex topography and apertures, the second process to fiberglass intended to be molded into simpler shapes.
- the fabric may be non-woven polyester with a thermoset binder, or it may be any durable, abrasion resistant fabric, such as nylon, rayon, and other synthetic fabrics, or natural fiber fabrics.
- the adhesive is preferred to be a water based, heat activated acrylic adhesive, but other known adhesives which are capable of withstanding the forces of the press and heated mold may be used and be within the scope of this invention.
- the molds are made of cast or machined aluminum, but epoxy, steel or other materials as are known in the art are also possible.
- the binder in the fabric is preferred to be a vinyl chloride copolymer, but other binders, in varying percentages, may be used within the scope of this invention.
- the completely enveloped and laminated fiberglass molded product is rendered abrasion resistant, non-irritating, and presents a smooth appearance. It is durable and easy to work with. There is no wrinkling or uneveness of fabric.
- the process described is applicable to any shaped mold used with a variety of qualities of fiberglass and a variety of binders, adhesives, and facing materials.
